“Turbomotor” rotary machine with volumetric expansion and variants thereof

Abstract

A “TurboMotor” positive displacement rotary-piston machine comprises a casing having an annular working chamber and intake and exhaust ports, two drive shafts coaxial with the annular surface defining the working chamber and provided with rotary pistons on one end thereof and with arms on the other end thereof, a stationary central gear coaxial with the surface defining the working chamber and with the drive shafts, an output shaft concentric with the drive shafts and having an offset portion carrying a carrier and a planetary gear, the planetary gear being in mesh with the stationary central gear the carrier being pivotally connected to the arms of both drive shafts through the connecting rods. The annular working chamber of the casing communicates with the intake ports and exhaust ports and/or exit channels and entrance channels arranged sequentially and contiguously.

 (e) the planetary gear being in mesh with the stationary central gear on the internal teeth thereof with a gear ratio i=n/(n+1), where n is a positive integer (i.e. n=1, 2, 3, 4, 5 . . . ), 
 (f) the carrier being pivotally connected to the arms of both drive shafts through the connecting rods, and 
 (g) the number of the rotary pistons mounted on each drive shaft being n+1, characterized in that 
 (h) the annular working chamber of the casing has intake ports and exhaust ports and exit channels and entrance channels to pass overflow content(s) carried out beyond the annular working chamber, 
 (i) the intake ports, the exit channels, the entrance channels, and the exhaust ports being sequentially and contiguously connected to the annular working chamber of the casing in the same direction as the rotary pistons move, 
 (j) the intake ports and the exhaust ports as well as the exit channels and the entrance channels being arranged on each side of the site where the sides of the rotary pistons close the respective intake and exhaust ports and the respective exit and entrance channels, 
 (k) and the sides of the rotary pistons in themselves having an angular width sufficient to simultaneously shutdown the exit channel and entrance channel. 
 
     
     
       2. The rotary-piston machine according to  claim 1 , characterized in that the exit channels and the entrance channels are formed as overflow chambers. 
     
     
       3. The rotary-piston machine according to  claim 2 , characterized in that the overflow chambers are mounted on hermetic heat-insulation gaskets, wherein the walls of the overflow chambers are lined with a highly porous gas-permeable and heat-resistant ceramic material. 
     
     
       4. The rotary-piston machine according to  claim 1 , characterized in that the annular working chamber of the casing is toroidal. 
     
     
       5. The rotary-piston machine of  claim 1 , characterized in that the casing has two stages where each stage has an annular working chamber wherein the first and second drive shafts and the rotary pistons are accommodated, wherein the output shaft has first and second offset portions carrying the respective carrier and the respective planetary gear in each of the multiple stages, the planetary gear being in mesh with the respective stationary central gear and the respective carrier being pivotally connected to the arms of the drive shafts through the connecting rods, and both of the stages of the annular working chamber and the first and second offset portions are set at an angle up to 180° relative to one another. 
     
     
       6. The rotary-piston machine of  claim 1 , characterized in that it comprises a geared power take-off shaft coaxial with the output shaft and carrying a gear wheel in mesh with an intermediate gear wheel positioned on the planetary gear. 
     
     
       7. The rotary-piston machine of  claim 1 , characterized in that the exit channels are connected through branch pipes to the inlet of a heater and the entrance channels are connected to the outlet of the heater, the intake ports being connected to the outlet of a cooler and the exhaust ports being connected to the inlet of the cooler. 
     
     
       8. The rotary-piston machine of  claim 1 , characterized in that there is a thermostatic throttle included between the outlet of a radiator and the entrance channels. 
     
     
       9. The rotary-piston machine of  claim 1 , characterized in that the exit channels are connected to an input manifold and the entrance channels are connected to an output manifold.
